seance.

.To all lwhom 'it may' concern: p

Beit known that Jenn J. RYAN, citizen of the United States, residing at Hons' ton, in the county of Harris and State of Texas, have invented certain new and useful Im rovements .in Gravity-Slide Ash- -Pans, o which the following is a speeilication.

.My invention relates to new and useful improvements in ash plans and more particue ash pan.

are caused to incline toward the center, thus tending to slide toward each other and keep the pan closed.

Finally the object of the invention is to provide a device of the character described that 'will be strong, durable and eflicient, and simple and comparatively inexpensive to produce, also one in which the several parts will not be liable to get out of working order.

lYith the above and other objects in view, the invention has relation to certain novel features of construction and operation, an. example of which is described in the speci. fication and illustrated in the accompanying drawings, wherein;

A Figure 1 is a side View of the ash pan, one half being shown in elevation and the other 2 is an end elevation, and Fig. 3 is a transverse sectional view.

In the drawings, the numeral 1 designates the ash pan which .is composed of inclined end castings 2 against which the usual doors 3l close, and sheet metal sides d. v

Intermediately arranged ridged guide castings 5 provided with downwardly in-y clined guide hangersl ti ,act in conjiunction with guide hangers 7 in slidably supporting valve plates 8. The guide hangersincline from each side of the pan to the longitudinal center thereof. It is obvious that this construction forms a plurality of hoppers and by sliding the plates Vlaterally the bottom of the ash pan may be opened and closed.` j

For. operating the valve plates, each `is providedwlth an year adapted to receivec'a pivotal connections and"v yoke link 10 having specification of Letters 'atent.

arm 11. These are mounted on rock shafts 12 extending longitudinallyon each side of the pan. These shafts are mounted in bearings 13 secured to the sides 1.

By rocking the shafts the valves are moved through the agency of the arms and the links. lt is obvious that1 the shafts may However, l prefer to mount on shafts 16 bell crank levers 1.4 having connection with links 15 pivotally connected .with the links '10., The shafts 16 are supported in bearings 17 mounted above the ash an.

At theirl upper end each bell crank has pivotedconnection with ia link 18 pivotally connected to the Vlower end of a piston rod 19. The piston rods prdject from steam or air pressure cylinders 20 mounted on the sides of the fire box 21 and having connection with steam or air supply and exhaust pipes Q2 connected with a controlling valve 23 which may be suitably located. By this means the piston rods are moved up and down and the bell crank levers swung in and out and the plates moved laterally atwill.

lt is apparent that the plates inclining downward will have a tendency to work or slide together and thus keep the bottom of the pan closed. Y

. l wish to call attention to the fact that the.

construction herein set forth permits of an easy and ready emptying of the pan and obviates the necessity of a man going under the panto empty and clean the same. The device may be used on various styles of ash pans as well as those of locomotives. l'."Vhat l claim is:

1. ltr-combination with an ash pan having bottom openingsseparated by a. member M arranged transversely of the pan between ends having oppositely disposed guides 3,-

the

other guide members 7 at the ends of pan, and two pairs oi' oppositely movente valve plates slidable 1n said guides to close the bottom openings of the pan, one pair of devoted to each opening. l2. In combination with an ash pan having bottom openings separated by a member 5 arranged transversely of the pan between its ends having oppositely disposed guides 6, other guide members 7 at the ends of the pan, and two pairs of oppositely movable valve plates slidable injsaid guidesto close thebottom openings of the pan, one pair of said vplates being devoted to each opening, @el/guides ,6 and 7 inclining from the oppoasr site ends thereof inwardly toward their centers, substantially as and for the purpose described.

3. In combination with an ash pan having bottom openings seprated by a member 5 arranged transversely of the pan between its ends having oppositely disposed guides 6, other guide members 7 at the ends of the pan, and' two pairs of oppositely movable valve platesvslidable in said guides to close the bottom openings of the pan, one pair of said plates being devoted to each opening, the guides 6 and 7 inelining from the oppol v chrections toward site ends thereof inwardly toward their oenters,4 and the bridging portion between the guides 6 nclinin downwardly in opposite the bottom' openings of the pans.

In testimony whereof I have signed my naine to this specification in the presence of zo two subscribing Witnesses.
